Where can I get the stock ECU flash for a 2004 WRX (USDM)

Postby snake2332 - n00b » Thu Mar 06, 2008 2:04 pm

I bought an '04 rex and it runs weird. I think the previous owner had it modded, then unmodded before selling it. Basically, my problem is: when I give it full throttle, the boost hits it's max then backs off to about half boost, then back to full boost then back to half boost, like it's hitting a limit and backing off. I bought a boost gauge but haven't received it yet, so I don't know how much boost it's producing. BTW, is AutoMeter GS series a decent boost gauge? I also got the install kit from wrxtra.com and a pod from subiegal.com.

So I am wondering if I can get a stock ROM file to flash my ECU with since my car is stock now. I will be modding it but want to start with it at stock. Will someone be willing to post/email me their 04 stock ROM file?

Thanks!

Look in the appropriate sub forum for that model, market, and year.

Oh ya, there they are. Sorry, I'm really new to all this and should learn to look before asking questions. :roll:

Boost Issue

I would check the vacuum lines between the boost solenoid and turbo. There is suppose to be a brass pill in the line. If the previous owner had a manual boost controller on the car he might no have put it back together properly.

I did replace those hoses and the pill since they were old and brittle. The previous owner had adjusted the wastegate arm a lot so I played with that until boost maxed out around 15 psi. Thanks for the tip though.
